[0002] Trusses are widely used in multiple fields such as machinery, electrical appliances, and construction. During the installation process of trusses, a truss connecting piece is required. The truss connecting piece is a crucial component in the truss structure. It is used to connect each component of the truss to ensure the stability and load-bearing capacity of the entire structure. Most of the existing truss connecting pieces adopt bolt connections, U-shaped threaded connecting pieces, etc. Connection holes are provided inside the truss, and the trusses are connected and installed by means of bolts or U-shaped threaded connecting pieces, etc.

[0003] The existing application number CN201720116387.6 discloses a truss connecting piece, which includes an intermediate connecting piece arranged in the middle position and rotary fixing pieces respectively connected to both ends of the intermediate connecting piece; the intermediate connecting piece includes an intermediate main body arranged in the middle position and clamping pieces arranged on both sides of the intermediate main body; the rotary fixing piece includes a rotary main body sleeved on the clamping piece, and a connection hole is arranged inside the rotary main body, and the shape of the connection hole is matched with the shapes of the intermediate main body and the clamping piece. For the present utility model, connection and loosening only need to rotate the sleeve, without the need to use a large number of pins or screws, nuts for connection and related installation tools.
